Datum Reference Level in Marks

Elevations in Marks

You can provide the relative distance to the view plane in part marks of parts in that view. This is commonly used when the top of steel values for beams differ slightly.

Adding datum reference values

In the View Properties, you will need to verify that you are using the View plane option for the Datum point for elevations: setting and it is providing the correct value in the Datum level field. If necessary, you can use the Specified option and input the needed Datum level value.



In the View Part Mark Properties you will need to add one of the level User-defined attributes to retrieve the offset values.
You can type one of the following into the User-defined attribute dialog depending on the top level value you need to report.
• TOP_LEVEL
• ASSEMBLY_TOP_LEVEL
• CAST_UNIT_TOP_LEVEL
• BOTTOM_LEVEL
• ASSEMBLY_BOTTOM_LEVEL
• CAST_UNIT_BOTTOM_LEVEL

Advanced Options

The variable XS_DRAWING_IGNORE_ZERO_LEVELS_IN_PART_MARKS can be used to control the display of zero values in marks that use the level attributes. In some of the Roles provide by the US environments this is set to TRUE by default which hides the zero levels in part marks while other roles have this variable set to FALSE in order to show those zero values.





Note that the surrounding text fields remain with the zero levels hidden and the notation may need to change or the process presented in the “Using Template in Marks” tutorial can be used.
